Thanks for all the input. After much reading, I think I'm going to start with the Xlab saddlewing attachment which allows me to choose my own water bottle cages. I went with a newer version of the Profile Design E-cage because it has a support arm running up the back which is supposed to help prevent the launching issues that happen using the Aquarack with the unsupported bottle holders (which others have complained that the bands which hold the bottles in breaks easily). I choose the Saddlewing because it looks like there's less bottle angle and allows for more room under that saddle for my small bag. Hopefully I won't have all the launch issues and can spend my time riding and not picking up my bottles. The hydration packs are perfect for when I'm offroading but didn't work as well for me on the road. I felt a little dorky too. If that doesn't work out, I'll try the Minoura dual cage mount ($13) that is vertical and attaches to the saddle arms. So far, I haven't found any negative reviews of it.
